Definitions
- the invention relates to a displacement air outlet with a housing having a Connecting piece and a plurality of arranged in an air outlet surface Has air outlet openings and by means of a perforated plate arranged therein in a Distributor space and a rectifier compartment is divided.
- Such displacement air outlets are well known and serve for low turbulence Blowing out the supply air, the blow-off speed is usually below 1 m / s. Due to the low blowing speed, the beam path is very strong Temperature difference between the supply air and the room air dependent. While in the cooling case compared to the room temperature cooler supply air tends to fall down, Escapes the supplied in the heating case with excess supply air to the ceiling area, so that it to an unsatisfactory warming of the occupied zone comes.
- displacement air outlets are usually made adjustable.
- adjusting mechanisms such as rotary valves, sliding Discs, sliding bezel rings, openable outlet bottoms and a pivoting of the entire blow-out element.
- the emerging from the core tube and the annular outlet opening rays can induce rays emerging from the perforated metal jacket such that they have a low-turbulence Displacement flow results.
- the invention has the object to provide a displacement air outlet, the is simple in its construction and yet an effective adjustment of the Air outlet direction allowed.
- the displacement air outlet according to the invention is thus a very simple possibility created to adjust the beam direction.
- the arranged inside the housing Perforated sheet is available anyway, even at displacement air outlets without any Adjustment to achieve a homogenization of the air outlet. With very simple constructive measures can be achieved by the removability of a portion of the perforated plate accomplish a very effective beam adjustment.
- a stepless removability of the perforated sheet metal section from the separation plane can thus, starting from a vertical outflow from the Air outlet surface, also achieve a stepless deflection of the air jet.
- the adjustment of the discharge direction is particularly effective and the spray pattern is particularly homogeneous when the portion of the perforated plate in an edge region of the perforated plate is arranged.
- the has a trapezoidal or semi-octagonal cross section and in which a rear wall a baseline of the trapezoid or a center line of the octagon forms, it is recommended that adjoining the rear wall sections of the trapezoidal or semi-octagonal Perforated sheets are hinged.
- Figure 1 shows a displacement air outlet 1 with a housing 2, which has a connection piece 3 and a plurality of air outlet openings 4, which in an air outlet surface. 5 are arranged.
- the air outlet surface 5 is formed by a perforated plate.
- the interior of the housing 2 is through a perforated plate 6 in a distribution chamber 7 and a Rectifier compartment 8 divided.
- the perforated plate 6 causes a homogenization of Air outlet from the air outlet openings 4, in which it is for a comparatively homogeneous Zu Kunststoffbeetzschlagung the rectifier compartment 8 provides.
- An upper portion 9 of the perforated plate 6 is pivotally mounted about a hinge 10 and leaves Therefore, partially or wholly from the separation plane defined by the perforated plate 6 between the distribution chamber 7 and the rectifier chamber 8 remove.
- the foldable Section 9 of the perforated plate 6 and the remaining perforated plate 6 have the same Hole diameter, so that in the fully folded position of the section. 9 makes a congruence, that is, that the holes of the touching Perforated sheet metal sections correspond with each other.
- Figure 2 it is shown that a horizontal outflow direction sets when the Section 9 of the perforated plate 6 is in the folded-up position.
- the displacement air outlet 1 shown the same beam characteristic as an outlet with a continuous rigid perforated plate 6 is equipped.
- Figure 4 shows a displacement air outlet 1 'with a cylindrical housing 2', whose shell-shaped air outlet surface 5 'is completely formed by a perforated plate.
- the inner Perforated plate 6 ' is also cylindrical and separates the inner distributor chamber 7' from the coaxially thereto arranged outer rectifier compartment 8 '.
- Two sections 9 'of the perforated plate 6 ' are rotatably mounted by means of hinges 10'. These sections are diametrically opposed opposite and have for reasons of folding not too long length. It is possible to have a plurality of pairwise diametrically opposite sections 9 ' to be provided, which are each mounted with separate hinges 10 'or the entire To move section parallel to the perforated plate 6 '.
- FIG 5 is still a section through a semi-octagonal Displacement air outlet 1 "shown, which also has a substantially half-octagonal inner perforated plate 6 "is provided in edge areas of the inner Perforated plate 6 ", which adjoin a rear wall 11 on both sides of the air connection piece 3, is in each case a pivotable portion 9 "of the perforated plate 6", with which in folded state a direct connection between the distribution chamber 7 "and the Rectifier room can be made 8 "Depending on the position of the hinged sections 9" can be the air jet emerging from the displacement air outlet 1 '' more or less far fan out.
